Cowboy World is a pen and paper role playing game about badass people kicking butt in the Old American West.
It is based on the Apocalypse World system.
It focuses on drama and conflict.
It is rules light.
Character creation is fast. You can play any genre-appropriate character you like.
It has no hit point system. Combat is fast, cinematic and deadly.
And if you want to play a game of weird steampunky horror set in the Old West, the last chapter, Going Weird, transforms Cowboy World into just that.
